php, getting a row from mysql and setting a variable to show a link

Question

ok can anyone see what im doing wrong here? just incase my coding is crap lol. what i have is a members website, the links are made based on wether the user is logged in or not. what im actually trying to achieve is getting the profile link to change by checking what account type the user has chosen at sign up

ive been at this for absolutely hours and im not sure what else i can try, im sure im on the right track but my php skills leave a lot to be desired

anyway heres my code and if anyone can help i would be eternally greatful, forgot what im trying to pass is $logOptions_account to achieve the link and the accounttype field in the database is the enum type if it makes a difference

mysql_query() returns a resource, not text.

$act = mysql_query // this is not text, so never "a, b, c ..."

$result = mysql_fetch_array($act) then $result['accounttype']

Prasad Rajapaksha · Accepted Answer · 2012-02-03 03:44:01Z

I would like to suggest you something too. It's about $act. You use it as String, MySQL Data set, and again as a Char. So if you use separate variables for different data types here it will be easy to manage. Of course you can do this with PHP. But I think my suggestion is a good practice.

Anyway when considering your code. Can you try changing bellow code.

$act = "";
$logOptions_account = $act;
$act = mysql_query("SELECT accounttype FROM memberstable WHERE accounttype='$logOptions_account' ");
if ($act == "a")

Here I see couple of issues.

$act = "";
$logOptions_account = $act;

See $act is a empty string. Then you assign it to $logOptions_account. So ultimately your query will be.

SELECT accounttype FROM memberstable WHERE accounttype=''

So you won't get result. You need to change that. I can't predict what are the exact values you have in $logOptions_account.

However if you correct that. You can continue with following kind of code.

$act = "";
$result = mysql_query("SELECT accounttype FROM memberstable WHERE accounttype='$logOptions_account' ");
while($row = mysql_fetch_array($result))
{
    $act = $row['accounttype'];
    if ($act == "a") {
    $logOptions_account = '<a href="fanprofile.php">';}
    else if($act == "b") {
    $logOptions_account = '<a href="artistprofile.php">';}
    else if($act == "c") {
    $logOptions_account = '<a href="bandprofile.php">';}
    else if($act == "d") {
    $logOptions_account = '<a href="businssprofile.php">';}
    else if($act == "e") {
    $logOptions_account = '<a href="venueprofile.php">';}
    else if($act == "f") {
    $logOptions_account = '<a href="serviceprofile.php">';}
    else {
    }
}

Above code is just an example for your understanding.

This is complete nonsense:

$act = ""; // is empty
$logOptions_account = $act; // both are empty
$act = mysql_query("SELECT accounttype FROM memberstable WHERE accounttype='$logOptions_account' "); // why you query for $logOptions_account(=$act) only to get $act again?
if ($act == "a") { // it is still empty, not "a"

And to get a row finally:

// make sure, that $logOptions_account has a valid value
$result = mysql_query("SELECT accounttype FROM memberstable WHERE accounttype='$logOptions_account' ");
if (!$result) {
    echo 'Could not run query: ' . mysql_error();
}
else {
  $row = mysql_fetch_row($result);
  if ($row['accounttype'] == "a") { ... }
  elseif ...
}

i feel i forgot to add that the accounttype field in mysql is of enum type, does that make a difference?

Normally, you should have only one row for each user, so this should do it ... see the example given here:
